Definitions

  • the invention relates to a modular ancillary, intended to allow the fitting of a knee prosthesis.
  • a knee prosthesis presupposes a prior surgical preparation, consisting in preparing the lower end of the femur, intended to receive the prosthesis.
  • this preparatory work consisting mainly in producing the surfaces of said end before making them complementary with the internal surfaces of knee prostheses, is carried out by means of an ancillary.
  • the ancillaries known to date are typically made up of at least two hundred parts, and prove to be difficult to handle and are also particularly expensive.
  • the object of the invention is to propose a modular, universal, compact ancillary, making it possible to precisely determine the importance in millimeters of the cuts to be made at the lower end of the femur.
  • the invention consists in proposing a modular ancillary, for which the different cutting variables, that is to say preparation of the end of the femur, functions of the patient to be operated on, are determined by means of sliding elements, the cuts to be made then being located by the installation of said sliding elements.
  • Figure 1 is a schematic perspective representation of the modular ancillary according to the invention.
  • Figure 2 is a schematic representation of a side view of the instrument of the invention.
  • Figure 3 is a schematic representation of a side view of the ancillary in place at the lower end of a femur during one of the preparation operations.
  • Figure 4 is a front view of the ancillary.
  • Figure 5 is a top view of the ancillary.
  • Figure 6 is a cross-sectional view of the distal cutting guide.
  • Figure 7 is a top view of the distal cutting guide.
  • FIG. 1 therefore shows a schematic perspective representation of the ancillary device according to the invention.
  • a slide (1) pierced in its center with a through light (2), aligned with the main dimension of the slide.
  • the light (2) is advantageously ovalized at its two ends.
  • This light (2) is intended to cooperate with a slide (3), the function of which is to guide a central medullary rod, represented schematically by the dotted line (27) in FIG. 3.
  • This slide (3) indeed has a hollow guide element (4), passing through said slide and emerging at the level of the light (2) of the slide (1).
  • the femur presents with respect to the mechanical axis of the leg, a deviation called valgus, typically spreading between individuals between 3 and 9 degrees. In this way, it is necessary to take this into account when placing a knee prosthesis.
  • the central medullary rod (27) must be guided to take account of this valgus.
  • the element guide (4) has a slight inclination relative to the normal of the slide (3). In the example shown, this slide is suitable for the installation of a right knee with a valgus of 7 °.
  • the slide (1) has at its lower end a template commonly called “template fork” (6), comprising two planar elements respectively (7) and (8), perpendicular to the slide (1), and intended to come s' press under the two external and internal condyles of the knee respectively when the joint is at 90 degrees of flexion.
  • template fork (6) is held integral with the slide (1) by means of a screw (9).
  • the slide (3) is provided with two symmetrical orifices (19) relative to the center of the slide (1), intended to receive compensation screws (18), so, during the insertion of the ancillary by insertion of the slide (3) on the central medullary rod (27), to compensate for the defects of the condyles, by resting on them, and this, to ensure correct and precise cuts of the femur. In addition, this ensures stabilization of the ancillary.
  • the upper end of the slide (1) receives a primary anterior cutting guide (10), capable of sliding on the slide (1), and fixable on the latter by means of lateral handles (11).
  • this anterior cutting guide (10) has on its anterior face a notch, for example of semi-cylindrical shape (14), intended to allow the reading of graduations (30) formed on the anterior face of the upper part of the slide (1).
  • This anterior cutting guide comprises at the lower part of its anterior face, two through slots respectively (12) and (13), intended to allow the passage of a saw to achieve, as will be described later, the leveling of the femur bone at the level of the anterior cortex.
  • the anterior cutting guide (10) is extended at its posterior face by a guide rod (15), comprising at its free end a feeler (16), intended to be positioned in contact with the cortical part. anterior part of the femur.
  • the other end (21) of the rod (15) is fixed to the anterior cutting guide (10).
  • This guide rod (15) is further intended to receive a distal cutting guide (17), capable of sliding along the rod (15) and of being also fixed on this rod (15), and this by means a screw (23), inserted into an orifice (29) formed in said guide, to come into contact with the rod (15).
  • the underside of the distal cutting guide (17) comprises a recess (28) in dovetail, intended to cooperate with the rod (15), of complementary shape. In this way, it favors the sliding of said guide and also its maintenance.
  • the distal cutting guide (17) also has on its upper part two sets of through orifices (24), each of the sets being in translation relation with respect to the other, and intended to allow the positioning of pins, to secure the distal cutting guide (17) at the femur (26) before making the distal cut from the end of the femur to be replaced.
  • These orifices (24) go in pairs, and correspond to marks making it possible to make a cut that is more or less in excess or, on the contrary, faulty in relation to the size of the prosthesis used.
  • the mode of operation of the ancillary device according to the invention will now be described in more detail.
  • the first step is to insert the central medullary rod (27) into the medullary canal of the femur (26).
  • insert the ancillary via the slide (3) on this rod, which emerges through the opening (5) of the guide element (4), then we proceed to its adjustment on the lower end of the femur, by resting the posterior condyles of the femur on the template fork (6,7,8), by making use of the compensation screws (18), if one of the two condyles is particularly worn, and by positioning the feeler (16) on the anterior cortex.
  • This adjustment makes it possible to correctly position the anterior cutting guide (10), in particular because the feeler is integral with the latter by means of the guide rod (15). Correlatively, it then makes it possible to carry out the reading at (14) of the graduation (30), indicating the size of the prosthesis to be used. We then proceed to the tightening of the handles (11).
  • the anterior cutting guide (10) is put in place and held by the handles (11), the anterior cortex of the femur (26) is cut, by inserting a saw in each of the slits (12) and ( 13) of said guide.
  • a section is thus obtained which is substantially parallel to the medullary canal, a section which level the bone at the level of the anterior cortex.
  • the distal cutting guide (17) is then placed on the guide rod (15), and it is positioned in contact with the anterior cutting guide (10). Then, the practitioner proceeds to fix this distal cutting guide by means of pins inserted in the orifices (24), in excess or in defect, or even corresponding to the very size of the prosthesis, depending on the condition of the patient's knee. Once this distal cutting guide (17) is fixed, the entire ancillary is removed, first by loosening the side handles (11), then sliding the guide rod (15) out of the dovetail recess (28) of said distal cutting guide. We then proceed to cut the distal part of the femur (26) by inserting a saw into the slot (22) of said guide.
  • cutting jigs adapted to each size are used to make the final cuts as well as two chamfers, intended to perfect the lower end of the femur to receive the knee prosthesis.
